REENFORCED BUILDING FABRIC.

Application iiledv February 20, 1922. Serial N'o. 537,717..

To aZZ 'whom t may\concem:

Be it known that I, EDWIN D. CODDING- TON, a citizen of the United States, residing at- North Milwaukee, in the countyv of Milwaukeevand State of Wisconsin, have invented certain new and useful Improvements in Reenforced Building Fabrics, of

which the following is a specification, reference being had to the accompanying drawing, forming a part thereof.

Thisinvention relates to substitutes for wood and metal lath of the class and for the general purposes of the reenforced fabric shown in United States Letters Patent No. 1,164,334, issued to me December 14:, 1915'. The main objects of the improvements constituting the present invention are to stii'en and lighten the construction of such reenforced fa ric and the walls or structures in which it is incorporated; to facilitateA the application of plaster or cement coatthinner coatings and thus edect a saving of plaster or cement; to provide 'for a more effective bonding of the plaster or cement to the fabric; to produce a reenforced fabric that will not shrink or buckle; and generally to improve building fabric of this class. y

It consists-in the construction, Larrangement and combination of parts as hereinafter particularly described and pointed out in the claims.

In the accompanying drawing like characters designate the same parts in the several figures.

yFigure 1 is an. elevation cr face view of I portions of adjoining sheets of reenforced building fabric embodying the invention as applied to the studding, frame-work or supporting structure of a wall, partition or roof; Fig. 2 is a vertical section on the line 2 2, Fig. 1; and Fig. 3 is a horizontal section on the line 3 3, Fig. 1.

The fabric comprises iiexible sheets aref suitable fibrous material, suchv as the well known building felt or paper of commerce,

.which is ordinarily and preferably saturated or coated with tar, asphalt or the like, to make it impervious to moisture.

The sheets are reinforced at suitable intervals with hard drawn resilient, or annealed or partially annealed and more or less flexible, metallic wires b', of any suitablepsize and cross section, woven in- .andA

out through the sheets. As shown by the accompanying drawing, the reenforcing wires b run cros'swise ofthe sheets parallel with one another and with the endsA or shorter edges ofthe sheets, but may be variously arranged and spaced, as illustrated in said Letters Patent, according to the character and purpose of the structure to which the fabric is applied.

Between one side of the sheets a. and the reenforcing wires b, auxiliary re'enforcing and stiii'ening 'strips c, of wood or other suitable non-metallic material of greater cross section than the wires are inserted lengthwise of the sheets and transversely to the wires, which.impart a corrugated or undulatoryform to the sheets, the stiifen `ing strips Vpassing through and deepening the depressions or undulatioris produced by the wires in the exposed sides of the sheets.'

To prevent the sheets a from loosely bellying or bulging outwardly too far, to increase `the stiil'ness and stability of the sheets and than through the inwardly sunken portions.

or depressions, thereby producing narrower and shallower undulations between' such depressions, and affording additional clenches for the plaster around the wires.

The wood or non-metallic stiiening strips c, being of4 greater width than the diameter of the wires,` aiiord convenient means for securely fastening the sheets to the studding or frame members ai of a partition, wall or other'structure, with staples e or nails f, as shown in Figs. 1 and 3.

The sheets a are lapped at their ends or shorter edges over the studs Z orv other frame members to which they are fastened, one edge of each sheet preferably extend.-

'ing beyond the stiiiening strips c and being overlapped by the adjoining sheet or sheets, so that the stiii'ening strips of each sheet may be placed end vto'end and inalignmentl overlapping edges' and terminate at the other end with the underlapping edges, thus formin in effect, continuous reenforcements paralle with the s tudding or frame members across the otherwise unsupported lap ed oints along the'sides of the sheets.

'Fogether the sheets a, reen-forcing wires b and stiffening strips c, forma beam-like structure producing a base or foundation sufficiently stiff or rigid and stable to withstand trowel pressure and to admit of the application of plaster in two coats instead of three ormore coats,v as required with other reenforced building fabrics or with metal lath, partial coatings g of plaster bein shown in Figs. 2 and 3.

he strips c are preferably left rough or are roughened, as by sawing, so that the plaster will adhere more firmly-to them, and their ,frictional engagement with the felt or paper sheets will be increased. ome or all of the stiffening strips may be dovetailed or beveled 'on one or opposite sides, as shown at the left in Fig. 2, or otherwise formed so as to afford a firmer clench or hold on the plaster which fills the depressions in the sheets on opposite sides n of the strips, and thus adds to the rigidity nection with buildin shown in Fig. 2.

and stability of the wall or structure.

The coefficient of friction between the wood or non-metallic strips c and the felt or paper sheets a, is much greater than that between the metal reenforcing wires I) and the sheets, and the resulting reenforced sheets are thus made much stiffer and firmer before as well as after the plaster coating is a pliedthereto.

T e plaster coating g fills the depressions in the sheets a and passes around and embeds the reenforcing wires b, thus making a strong bond with the reenforced fabric and stilfffening and strengthening the coating itse The reenforced fabric may be used to advantage in connection with brick-veneered walls, or as shown in Figs. 2 and 3, in conboard 71., such as Celotex, Flaxilinum and the like, for added protection against the transmission of heat, moisture andv sound.

.Additional wood or non-metallic stiffening strips z', may be attached or fastened to the sheets a, on the opposite sides thereof from the strips 0, particularly when it is desired to'plaster'both sides of the fabric, as

1. A reenforced building fabric compris* enforcing wires woven through the. sheet at intervals and imparting an undulatory form v ing through 'the outwardly bulged portions of the sheet at closer intervals and forming ,shallower undulations therein than the depressed portions in which vthe stiffening` strips are located.

- 3. A reenforced building fabric comprising a flexible sheet of fibrous material,-reenforcing wires woven at intervals through the sheet and imparting an undulatory form thereto, and non-metallic stiffening strips of greater cross section than the wires inserted between the wires and one side of the sheet, the whole forming a stiff beam-like structure.

4. A reenforced building fabric comprising a flexible sheet of fibrous material, re-

enforcing wires woven through the sheet and imparting an undulatory form thereto and auxiliary nailing and stiffening strips of greater width than the diameter of the wires inserted in depressions in one side of the sheet between it and the wires transversely to the wires.

5. A reenforced building fabric comprising a flexible sheet of fibrous material, reenforcing wires woven throu h` the .sheet and imparting an undulatory orm theretp, and non-metallic` stiffening strips of olygo- `nal form and greater cross sectiont an the wires inserted in depressions ,in the sheet between one side thereof and the wires, and forming therewith a firm beam-like structure.

6. A reenforced building fabric comprising a flexible sheet of fibrous material, meta ic reenforcing wires woven through the sheet and imparting an undulatory form thereto, and wooden vstifl'ening strips of greater cross section than the wires inserted between the wires and sheet transversely to the wires and having roughened surfaces.

7. A reenforced building fabric comprising a flexible sheet of fibrous material, reen orcing wires woven through the sheet and imparting an undulatory form thereto, non-metallic stifening strips of greater cross section than the wires inserted between the wires and one side of the sheet transversely to the wires, and similar stiffening strips attached to the opposite side of the sheet. e A

8. A reenforced building fabric compris- .ing a flexible undulatory sheet of fibrous material, and reenforcing wires woven through the sheet, the wires passing through the outwardly bulging portions of the sheet at shorter intervals and forming narrower and shallower undulations therein than in the intervening inwardly depressed portions.

9. A reenforced building fabric comprising; a Ilexibie undulatory sheet of ibrons material, reenforeing Wires Wbventhrug'h the sheet, und non-metallic stiffening strips of greater cross seetionthan the Wires inserted between the wires and one side of the sheet and terminating at one end short ot one edge of the sheet :md at the other end substantially even with the opposite edge of the sheet` wherebyl the edges of adjoining sheets may be lapped and the reenforc- 10 ing strips thereof. arranged in alignment.

In witness whereof I hereto aix my signature.
